I think I'll try with just 2D figures first to see if I can get that 
working. I haven't been able to get the camera working yet. I'm not 
really sure how well my Mac setup is working..I've only been able to 
get the 2 1/2 D diagrams working.

But for example if I'm calling invalidate on the root edit part that 
won't force for the childre -- I'll need to use invaidateTee for that..

But yeah, it seems wasteful to walk the whole tree (I've got thousands 
of figures) to invlidate and then walk again to re-render.

Do I need to call render explicitly as well?

thanks!
